OCanren can be installed using opam (>= 2.1). First, install opam itself, initialize it and install right compiler version.

  • opam init --bare if your opam has not been initialized before

  • opam switch create 4.14.1 --packages=ocaml-variants.4.14.1+options,ocaml-option-flambda installes right compiler. (4.14.1 is a custom switch identifier)

  • eval $(opam env) updates an environment. Opam will put the invocation of this command to your ~/.bashrc.

  • check that ocamlc -v prints right compiler version

Then, install dependencies and OCanren:

  • git clone

  • cd OCanren

  • Install GT dependency (pick one command)
    • git clone to use GT as a vendored library.

    • opam install GT -y to install GT from the main opam repository.

  • opam install . --deps-only --yes

  • make

  • make tests

Expected workflow:
